Which pair of organelles is found in plant cells but not in animal cells?

• A. Lysosomes and centrioles
• B. Chloroplasts and a large central vacuole
• C. Mitochondria and rough endoplasmic reticulum
• D. Golgi apparatus and ribosomes

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the question is asking to identify organelles that are present in plant cells but absent in animal cells.
2. Step 2: Recall that chloroplasts are organelles responsible for photosynthesis and are unique to plant cells and some protists, not found in animal cells.
3. Step 3: Recognize that a large central vacuole is a prominent feature in plant cells, used for storage and maintaining cell rigidity, but animal cells have smaller or no central vacuoles.
4. Step 4: Note that lysosomes, centrioles, mitochondria, rough endoplasmic reticulum, Golgi apparatus, and ribosomes are found in both plant and animal cells, so they are not unique to plant cells.
5. Step 5: Conclude that the pair of organelles unique to plant cells among the options given is chloroplasts and a large central vacuole.
